ANTISKIDDING DEVICE.

Specification of Letters Patent.

Patented Jan. 4, 1910.

' Application filed December 5, 1906. Serial No. 346,501.

,lie it known that I, EDWIN BALL STIMP- sonV citizen of the United States, residing in me borough of Brooklyn, city and State of New York, have :invented a certain new and useful Antiskidding Device, of whichthe following is a specification.

My'present invention relates to a new entiskidding device for use in connection with the tires of automobiles and other vehicles.

In the drawings, Figure 1 is a perspective view ofthe device, showing its two parts un# assembled, and Fig. 2 is a transverse section ot' the devicepositioned on the tire.

Describing now iny invention with partisular reference to the drawlng, and reserv ing it to the claim to point out the novel features and to define the scope of the invention,

the anti-slcidding device shown comprises f twoV parts, a bent rod l and a base plate 3. The bent rod l has downwardly extending Shanks 2 at either end positioned to be receired through openings at' in the base plate.

.lhe intermediate portion connectin the slnxnks 2 of the bent rod is not straightut is bent, or crooked, laterally in a plane substan tially 'parallel with the plane of the base plate when the two parts of the device are assembled.

To use the device, the shrinks .2 of the bent rod are inserted through suitable openings made in the tire with the crooked connecting portieri of the rod resting upon the outside of the tire m in road-contacting position. The base plate is then applied 'to the underside ofthe tire material with the free ends of the shanks 2 received into the openings et in the base plate. und being clenched to hold the two parts of the device inseperably t0- gether.

'It will be noted that preferably tbe roadcontacting'part of the device is made of round rofl material whereby no sharp edges or corners are presented by it to the tire inaterial to out the tire.

^ The fact that the connecting, or intermediate, portion between the Shanks 2 of the bent rod member is bent laterally out of a straight line, is to give the eil'ect of clamping the tire material between two extended surfaces so that rocking of the device on the tire during. its running is reduced to a minimum, and consequently the -tire materiel is saved from frictional -wear and abrasion to the seine extent. In addition, the laterally bent road-contacting part has improved gripping \\q`uality bothy for the forward drive and as better tending to prevent skidding. .It will /bennderstood that tires are to be equipped' with a-plurality of devices like that described etending all around the tread of the tire.

Having thus described my'invention, what 1 claim is:v -V

An anti skidd'ing device comprising a metal strip having its ends bent to pass through the tire material withr its intermediate portion next the outside of said material, said portion being bent laterally out of a straight line; and a base plete having openings adapted to receive therethrough the extremities of the bent ends of the strip, said extremities being ada ted tti be clenched against the underside QI the J ate. l In witness whereof I have hereunto sxgied my namevthis 4th dey of Dec. 1906, i. f he EDWIN BAL vSTIMPSON.
